The SINCLAIR INTERNATIONAL 223 REMINGTON O-RING ROD GUIDE is designed to seal the barrel from the receiver, preventing solvent leakage into the action area.
It fits a wide range of actions and cartridge families, with specific machining for over 1000 combinations, and includes integral solvent ports.
Custom rod guides are available without solvent ports upon request, with a 2-4 week delivery time at no extra charge, but FN Model 70 post-2010 requires a custom guide.
